[Isotope nephrographic investigations after experimental unilateral fractionated irradiation of a kidney (author's transl)].

The left kidneys of rabbits were fractionally irradiated to a total dose of 6.000 R. Renal function was regularly monitored by isotope nephrography. Semiquantitative measurements (Zum Winkel) and comparison to the two sides (Bargon and Emrich) show changes in renal function in the functional and excretory phases; these, however, were less marked than after single dose irradiation. The results are discussed with reference to the relevant literature.
